Abstract

Volatile constituents of the dried tuberous tap-root, leaf and seed of cultivated Brassica rapa L. ssp. rapa collected after hydrolysis were analyzed by GC and GC/MS. The major volatile constituents of the root were 2-phenylethyl isothiocyanate (32.6%), sec-butyl isothiocyanate (25.7%), 4-pentenyl isothiocyanate (12.8%), 5-methylthiopentyl isothiocyanate (10.0%) and 2-hexenal (4.6%), while the major volatile components of the leaf oil were 4-pentenyl isothiocyanate (53.7%), sec-butyl isothiocyanate (24.3%) and 3-butenyl isothiocyanate (15.8%). The main volatile constituents of the seed were 3-butenyl isothiocyanate (59.7%), 4-pentenyl isothiocyanate (31.0%) and sec-butyl isothiocyanate (1.7%). © 2010, Taylor & Francis Group, LLC.
